This reminds me of an exchange in the movie Tommy Boy with the late, great Chris Farley.
Tommy: Let’s think about this for a sec, Ted, why do they put a guarantee on a box? Hmm, very interesting.
Ted: I’m listening.
Tommy: Here’s how I see it. A guy puts a guarantee on the box 'cause he wants you to fell all warm and toasty inside.
Ted: Yeah, makes a man feel good.
Tommy: 'Course it does. Ya think if you leave that box under your pillow at night, the Guarantee Fairy might come by and leave a quarter.
Ted: What’s your point?
Tommy: The point is, how do you know the Guarantee Fairy isn’t a crazy glue sniffer? “Building model airplanes” says the little fairy, but we’re not buying it. Next thing you know, there’s money missing off the dresser and your daughter’s knocked up, I seen it a hundred times.
Ted: But why do they put a guarantee on the box then?
Tommy: Because they know all they sold ya was a guaranteed piece of #*$&. That’s all it is. Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for right now, for your sake, for your daughter’s sake, ya might wanna think about buying a quality item from me.
Ted: Hmm. Okay, I’ll buy from you.
Tommy: Well I… What?
